LIN'ARD ALPHONSE HUBER/I, OF TBOYES, FRANCE.

GANG-PLOW.

To all whom it may concern:

Be it known that I, LINARD ALPHoNsE HUBERT, a citizen of the FrenchRepublic, and resident of Troyes, France, have invented certain new anduseful Improvements in and Relating to Gang-Plows, of which thefollowing is a specification.

This invention relates to improvements in gang plows and has for itsobject the provision of a construction whereby the plow shares arevibrated when turning over the soil for the purpose of reducing thepower necessary to advance the plows. The vibration of the plow sharesserves to effectively cut the sod and turn the soil with a greatlyreduced amount of power when compared to prior methods of applying adirect and con stant pull to the plows.

The structure according to my improved device enables the dispositlon ofthe plows in a straight line and avoids the oblique arrangement of theplow shares heretofore necessary.

The invention will be more fully described in connection with theaccompanying drawings and will be more particularly pointed out andascertained in and by the appended claims.

In the drawings :F igure 1 is a view in side elevation of a gang plowembodying the main features of my invention. Fig. 2 is a plan viewthereof.

Like characters of reference designate similar parts throughout thedifierent figures of the drawings.

As shown cl designates an axle upon which drive-wheels Z) are mountedfor the purpose of advancing the plow structure over the field. The axlecl is provided with sprocket wheels 3 driven by chains 2 from sprocketpinions 1, the latter being mounted on shaft 2. A gear wheel y, mountedon shaft 2 meshes with a gear wheel X mounted upon shaft 13. The shaftsa and 13 are mounted in the main frame a which is supported by the axle(Z and the steering wheels 0. The shaft 13 carries a sleeve 14, which isslidably and non rotatably mounted thereon, and said sleeve 14 isprovided with bevel gears o and o. A lever 14 is connected with thesleeve 14: to shift the same on the shaft 13. A driving shaft t isindicated, which may be driven from any suitable source of power, and isprovided with a bevel pinion to adapted to mesh with bevel gears 42 and'0 when the sleeve 14% is shifted on the shaft 13.

sleeve let also carries a gear wheel 4: which meshes with a gear wheel 5and said gear wheel 5 is mounted upon a sleeve 5 which carries avibrator s. Said sleeve 5 is nonslidably and rotatably mounted upon theaxle (Z. As shown power is transmitted through bevel gears 26, o andsleeve 14 to shaft 13 and from shaft 13 through gears X, Y to shaft 2.Shaft e acting through sprocket pinions 1 and chains 2 drives sprocketwheels 3 and axle (Z and wheels I; forwardly. \Vhen the sleeve 14 isshifted to bring the bevel gear o into mesh with the pinion u the gear 4is thrown out of mesh with gear 5 and power is transmitted throughpinion u to o and thence through shaft 13 and gears X, Y, 1 and chains 2and sprockets 3 in a reverse direction from the adjustment firstdescribed and the adjustment shown. It will be seen that when the piniona meshes with the pinion o the wheel 5 will be rotated as this would bethe adjustment used when the plow structure is advancing in a forwarddirection but when the reverse adjustment is desired the wheel 5 willnot be operated and the gear connection shown will drive the wheels I)in a rearward direction.

A plow frame is provided which consists of a transverse membere to theends of which extensions f are mounted. The plow shares are mounted onthe extensions f as will hereinafter more fully appear. Extensions f aremounted upon the axle (Z so as to be swung around the same. An adjustingframe 6 is mounted upon the axle (Z and is connected with the innermostextensions f" and at its forward end said frame 6 is connected by a link7 to an adjusting lever 8, pivotally mounted at 9. The adjusting lever 8is provided with a rack 10 adapted to be engaged by a pawl 11 pivotallymounted upon the frame a. It will be seen that by adjusting the lever 8in the direction of the arrow 10 that the frame 6 will be depressed andthe extensions will be raised. The pawl does not serve to lock the lever8 in any position of adjustment.

A rod 15 is fixed to the extensions f and sleeves g are loosely mountedupon said rod. Plow shares 2' are supported from the sleeves g by meansof clamp collars j embracing the sleeves g and adapted to be tight--ened or fixed thereon by threaded rods.

76. A reversible vibrating member Z is fixed to the sleeves g and isrotatably mounted on the rod 15 and said member Z is provided at itsopposite ends with loops Z in the end walls of which apertures m areformed. An

vibrator s. Said arm a 72 extends through either of the apertures mandis locked therein by a nut 0. The arm 79 may be provided with a pivotedmember a having a handle and a threaded extension on which the nut 0 maybe secured. It will be seen thatby disengaging the nut 0 the sleeves 9may be rotated by the member Z to bring either set of plows into action.It will also be obvious that when the axle d is rotated the vibrator swill impart vibratory movement to the connections e and Z so as tovibrate the plows i continuously.

I claim 1. A gang plow comprising in combination, driving wheels and anaxle therefor, a driving shaft, means operatively interposed betweensaid axle and driving shaft for driving the former in reversedirections, a main frame mounted on said axle, a plow frame mounted onsaid axle, a plurality of sets of plows mounted on said plow frame, theplows of each set being arranged in transverse alinement with respect tothe longitudinal axis of the gang plow, means connecting the plow framewith the main frame to tilt the former, means for throwing either setsof plows into or out of an operative position, and means for impartingcontinuous vibratory movement to said plows.

2. A gang plow comprising in combination, driving wheels and an axletherefor, means for driving said axle, a main frame mounted on saidaxle, a plow frame mounted on said axle, a plurality of sets of plowsmounted on said plow frame, the plows of each set being arranged intransverse alinement with the longitudinal axis of the gang plow, meansfor throwing either sets of plows into or out of an operative position,and means for imparting continuous vibratory movement to said plows.

3, A gang plow comprising in combination, driving wheels and an axletherefor,

means for operating said axle, a main frame mounted on said axle, a plowframe mounted on said axle, plows mounted 011 said plow frame intransverse alinement with respect to the longitudinal axis of the gangplow, and means imparting continuous vibratory movement to said plows.

In testimony whereof I have hereunto set my hand in presence of twowitnesses.
